At road.cc every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.What the road.cc scores mean
Good scores are more common than bad, because fortunately good products are more common than bad.
Thin and lightweight yet warm, the Lusso Thermal Skull Cap is an ideal piece of kit for when the temperatures drop to near freezing and you want to avoid that ice-cream headache.
The majority of helmets are designed with massive vents to allow heat to escape in summer, so it's no wonder that in the middle of winter when riding into an icy wind their performance can be sub-par. That's when you need something like a skull cap.
The skull cap is nothing new and Lusso hasn't exactly come up with anything ground-breaking with this version, but if it ain't broke, why fix it?
The material used here is relatively thin so you aren't adding a huge amount of bulk underneath your helmet – in fact, on most of mine I only needed to loosen the cradle by a couple of clicks.
There is a bit of stretch in the material so you get a good snug fit without it really adding any pressure around your forehead or temples. Over the ears there is a little bit of room so that they don't feel squished, and if you wear earphones on the bike like I do then they aren't being pressed into your ears any further than you want them to be.
The seams are well positioned and I didn't have any irritation with any helmets rubbing them against my head, even on long rides.
Overall warmth is pretty much spot on too: just enough to take the chill off without seeing you start to sweat as soon as the ride intensity increases.
The whole thing packs up really small as well, so if you do start to overheat you can easily whip it off and stick it in a back pocket.
For value, I don't think you can really argue that £9.99 isn't a good deal. It's well made here in the UK and it does the job it's designed to do – and just as well as the £40 Assos RoboCap.
It's cheaper than the very good Galibier Dolomiti Skull Cap, too, which currently costs £12.77.
Overall, the Lusso Thermal Skull Cap does the job, is comfortable to wear and doesn't cost the earth.
Simple, well-priced solution for keeping your head warm in freezing conditions

With 20 years of road cycling and over 150,000 miles in his legs it's safe to say Stu is happiest when on the bike whatever the weather. Since writing his first review for road.cc back in 2009 he has also had a career in engineering including 3D-CAD design and product development, so has a real passion for all of the latest technology coming through in the industry but is also a sucker for a classic steel frame, skinny tyres, rim brakes and a damn good paintjob.
His fascination with gravel bikes is getting out of control too!
